Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘Yoguide’.

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is co-pending with the following relatedapplications: Title: Chrysanthemum Plant Named ‘Yodigit’. Applicant:Cornelis P. VandenBerg.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofChrysanthemum plant, botanically known as Chrysanthemum×morifolium andhereinafter referred to by the name ‘Yoguide’.

The new Chrysanthemum is a product of a planned breeding programconducted by the Inventor in Salinas, Calif. and Alva, Fla. Theobjective of the breeding program is to create new cut Chrysanthemumcultivars having inflorescences with desirable colors and goodinflorescence form and substance.

The new Chrysanthemum originated from a cross-pollination made by theInventor in May, 1995, in Salinas, Calif., of theChrysanthemum×morifolium cultivar Alma, not patented, as the female, orseed, parent with a proprietary selection of Chrysanthemum×morifoliumidentified as code number 1849, not patented, as the male, or pollen,parent.

The cultivar Yoguide was discovered and selected by the Inventor as aflowering plant within the progeny of the stated cross-pollination in acontrolled environment in Alva, Fla., in April, 1996. The selection ofthis plant was based on its desirable inflorescence color and goodinflorescence form and substance.

Asexual reproduction of the new Chrysanthemum by terminal cuttings in acontrolled environment in Alva, Fla. since June, 1996, has shown thatthe unique features of this new Chrysanthemum are stable and reproducedtrue to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Yoguide have not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, daylength and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Yoguide’. These characteristics incombination distinguish ‘Yoguide’ as a new and distinct cultivar:

-   -   1. Upright cut Chrysanthemum that is usually grown as a natural        spray.    -   2. Dark green-colored foliage.    -   3. Freely flowering habit, about eight inflorescences per        flowering stem.    -   4. Uniform inflorescence form and development.    -   5. Small daisy-type inflorescences that are about 4.1 cm in        diameter.    -   6. Attractive bright yellow-colored ray florets.    -   7. Response time about nine weeks.    -   8. Strong peduncles.    -   9. Good postproduction longevity with inflorescences and foliage        maintaining good substance and color for about three weeks in an        interior environment.

Compared to plants of the female parent, the cultivar Alma, plants ofthe new Chrysanthemum have slightly smaller inflorescences, are morefreely and uniformly flowering and flower about two days later. Inaddition, plants of the new Chrysanthemum and the cultivar Alma differin ray floret coloration as plants of the cultivar Alma havewhite-colored ray florets.

Compared to plants of the male parent selection, plants of the newChrysanthemum have smaller inflorescences and are more freely flowering.In addition, plants of the new Chrysanthemum and the male parentselection differ in ray floret coloration as plants of the male parentselection have white-colored ray florets.

Compared to plants of the cultivar Yodigit, disclosed in a U.S. Plantpatent application Ser. No. 11/122,825, plants of the new Chrysanthemumdiffer primarily in ray floret coloration as plants of the cultivarYodigit have white-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of theChrysanthemum×morifolium cultivar Yellow Vero, disclosed in U.S. PlantPat. No. 6,943. In side-by-side comparisons conducted in Alva, Fla.,plants of the new Chrysanthemum differed from plants of the cultivarYellow Vero in the following characteristics:

-   -   1. Plants of the new Chrysanthemum had smaller inflorescences        than plants of the cultivar Yellow Vero.    -   2. Plants of the new Chrysanthemum were more freely flowering        than plants of the cultivar Yellow Vero.    -   3. Plants of the new Chrysanthemum had shorter peduncles than        plants of the cultivar Yellow Vero.    -   4. Ray floret color of plants of the new Chrysanthemum was        darker than ray floret color of plants of the cultivar Yellow        Vero.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The RoyalHorticultural Society Colour Chart, 1995 Edition, except where generalterms of ordinary dictionary significance are used. The aforementionedphotographs and following observations and measurements describe plantsgrown in Salinas, Calif., under conditions which approximate commercialpractice in a polyethylene-covered greenhouse. Two-week old rootedcuttings were planted on Dec. 30, 2004 and received about two weeks oflong day/short nights followed by short day/long nights until flowering.Plants were grown as single-stem natural spray cut Chrysanthemums.During the production time, the following environmental conditions weremeasured: day temperatures, 24 to 27° C.; night temperatures, 10 to 16°C.; and light levels, 2,000 to 4,000 foot-candles. Measurements andnumerical values represent averages for six to ten typical floweringstems and were taken about nine to ten weeks after the start of shortdays.
